Quantum Field Theory, 2nd Edition

Following on from the successful first (1984) and revised (1993)
editions, this extended and revised text is designed as a short and
simple introduction to quantum field theory for final year physics
students and for postgraduate students beginning research in
theoretical and experimental particle physics.

The three main objectives of the book are to:

Explain the basic physics and formalism of quantum field
theory

To make the reader proficient in theory calculations using
Feynman diagrams

To introduce the reader to gauge theories, which play a central
role in elementary particle physics.

Thus, the first ten chapters deal with QED in the canonical
formalism, and are little changed from the first edition. A brief
introduction to gauge theories (Chapter 11) is then followed by two
sections, which may be read independently of each other. They cover
QCD and related topics (Chapters 12-15) and the unified electroweak
theory (Chapters 16 – 19) respectively. Problems are provided
at the end of each chapter.

New to this edition:

Five new chapters, giving an introduction to quantum
chromodynamics and the methods used to understand it: in
particular, path integrals and the renormalization group.

The treatment of electroweak interactions has been revised and
updated to take account of more recent experiments.
